Android Nougat 7.1.2
Following Android Alpha and Android Beta, Google has always named its Android OS updates after sweet treats, and in alphabetical order. So far we've had Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow and Nougat
Google released Android Nougat in August, and has now released Android Nougat 7.1.1 and a beta version of Android Nougat 7.1.2.
Google has released Android Nougat 7.1 to the Nexus 5X, Nexus 6P and Pixel C, with support coming for other Google devices in early 2017.
New features include instant chat support, automatic data uploading to the cloud and Daydream VR support, plus a host of features that will excite devs, such as custom shortcuts, support for image keyboards, and APIs for multi-endpoint calling and telephony configuration.
Also available now is a public beta of Android 7.1.2, which should be released within the next few months. It is said to be "an incremental maintenance release focused on refinements, so it includes a number of bugfixes and optimizations, along with a small number of enhancements for carriers and users".
